In this study, a hybrid machine learning (HML)-based approach, incorporating Genetic data analysis (GDA), is proposed to accurately identify the presence of adenomatous colorectal polyps (ACRP) which is a crucial early detector of colorectal cancer (CRC). The present study develops a classification ensemble model based on tuned hyperparameters. Surpassing accuracy percentages of early detection approaches used in previous studies, the current method exhibits exceptional performance in identifying ACRP and diagnosing CRC, overcoming limitations of CRC traditional methods that are based on error-prone manual examination. Particularly, the method demonstrates the following CRP identification accuracy data: 97.7 ± 1.1, precision: 94.3 ± 5, recall: 96.0 ± 3, F1-score: 95.7 ± 4, specificity: 97.3 ± 1.2, average AUC: 0.97.3 ± 0.02, and average p-value: 0.0425 ± 0.07. The findings underscore the potential of this method for early detection of ACRP as well as clinical use in the development of CRC treatment planning strategies. The advantages of this approach are highly expected to contribute to the prevention and reduction of CRC mortality.

In recent years,fossil fuels such as petroleum,coal,and natural gas have become limited *** addition, global warming due to carbon dioxide (CO) emission has become a serious environmental *** current living and economical standards depend strongly on fossil energy sources,it is necessary to realize a new society that utilizes biomass as a source of energy. With this background,in 2005,we manufactured a practical Stirling engine using biomass *** we proposed a tmique co-generation system using a practical Stirling engine that utilizes woody biomass fuel such as sawdust, firewood,and wood pellets.A burner uses the woody biomass fuel to heat the air in the expansion room to about 650℃ and a water cooling system cools the air in the compression room to about 40℃.Under these operating conditions,the new engine generated about 3kW of electricity.

AIM:To investigate the reasons for the occurrence of the pink-color sign of iodine-unstained lesions. METHODS:In chromoendoscopy, the pink-color sign of iodine-unstained lesions is recognized as useful for the diagnosis of esophageal squamous cell carcinoma. Patients with superficial esophageal neoplasms treated by endoscopic resection were included in the study. Areas of mucosa with and without the pink-color sign were evaluated histologically. The following histologic features that were possibly associated with the pinkcolor sign were evaluated. The keratinous layer and basal cell layer were classified as present or absent. Cellular atypia was classified as high grade, moderate grade or low grade, based on nuclear irregularity, mitotic figures, loss of polarity, chromatin pattern and nuclear/cytoplasmic ratio. Vascular change was assessed based on dilatation, tortuosity, caliber change and variability in shape. Vessels with these four findings were classified as positive for vascular change. Endoscopic images of the lesions were captured immediately after iodine staining, 2-3 min after iodine staining and after complete fading of iodine staining. Quantitative analysis of color changes after iodine staining was also performed. RESULTS:A total of 61 superficial esophageal neoplasms in 54 patients were included in the study. The lesions were located in the cervical esophagus in one case, the upper thoracic esophagus in 10 cases, the mid-thoracic esophagus in 33 cases, and the lower thoracic esophagus in 17 cases. The median diameter of the lesions was 20 mm (range:2-74 mm). Of the 61 lesions, 28 were classified as pink-color sign positive and 33 as pink-color sign negative. The histologic diagnosis was high-grade intraepithelial neoplasia (HGIN) or cancer invading into the lamina propria in 26 of the 28 pink-color sign positive lesions. There was a significant association between pink-color sign positive epithelium and HGIN or invasive cancer (P = 0.0001). Univariate

＜正＞ By means of perceptual experiments, we investigated what range of modulation frequency components of the melfrequency cepstral coefficients （MFCC） contains the most important information for speaker identification. In our study, wc conducted two perceptual experiments using an MFCC-based re-synthesis scheme with two types of excitation. In Experiment Ⅰ, speech sounds were resynthesized from the extracted pitch and while noise. In Experiment Ⅱ, speech sounds were re-synthesized only from white noise to avoid including pitch information. For each experiment the original speech sounds were uttered by two sets of five professors. A total of 44 students （16 for Exp. Ⅰ and 28 for Exp. Ⅱ） who attend the professors’ classes participated in the experiments. We analyzed the experimental results in order to estimate the relative importance of different modulation frequencies in speaker recognition. The results show that the most important speaker information was in modulation frequency components from 2 to 8 Hz for both Exp. Ⅰ（pitch-excited） and Exp. Ⅱ（noise-excited）. These results also show that some contribution was derived from including modulation frequency components around 0 Hz. Hence, we concluded that dynamic features are important for human speaker identification as well us static features.

AIM： To study the regulatory mechanisms of sinusoida regeneration after partial hepatectomy. METHODS： We invesldgated the expression of angiopoietin （Ang）-1, Ang-2, Tie-2, and vascular endothelial growth factor （VEGF） in regenerating liver tissue by quantitative reverse-transcription polymerase chain reaction （RT- PCR） using a LightCycler （Roche Diagnostics） and also immunohistochemical staining after 70% hepatectomy in rats. In the next step, we isolated liver cells （hepatocytes, sinusoidal endothelial cell （SEC）, Kupffer cell, and hepatic stellate cells （HSC）） from regenerating liver tissue by in situ collagenase perfusion and counterflow elutriation, to determine potential cellular sources of these angiogenic factors after hepatectomy. Proliferation and apoptosis of SECs were also evaluated by proliferating cell nuclear antigen （PCNA） staining and the terminal deoxynucleotidyl transferase d-uridine triphosphate nick end labeling （TUNEL） assay, respectively. RESULTS： VEGF mRNA expression increased with a peak at 72 h after hepatectomy, decreasing thereafter. The expression of Ang-1 mRNA was present at detectable levels before hepatectomy and increased slowly with a peak at 96 h. Meanwhile, Ang-2 mRNA was hardly detected before hepatectomy, but was remarkably induced at 120 and 144 h. In isolated cells, VEGF mRNA expression was found mainly in the hepatocyte fraction. Meanwhile, mRNA for Ang-1 and Ang-2 was found in the SEC and HSC fractions, but was more prominent in the latter. The PCNA labeling index of SECs increased slowly, reaching a peak at 72 h, whereas apoptotic SECs were detected between 120 h and 144 h. CONCLUSION： Ang-Tie system, together with VEGF, plays a critical role in regulating balance between SEC proliferation and apoptosis during sinusoidal regeneration after hepatectomy. However, the VEGF system plays a more important role in the early phase of sinusoidal regeneration than angiopoietin/Tie system.

本文研究烧结矿经卤化钙水溶液或悬浮液浸泡后再干燥处理对其还原粉化指数(RDI)及相对还原率(RI)的影响。烧结矿的浸泡处理是在室温下、空气和真空中进行的。卤化钙水溶液或悬浮液的浓度变化范围为1.0～10.0(wt)％。烧结矿在CaCl_2和CaBr_2水溶液中浸泡后,其RI值保持不变,而RDI值降低,也就是说,在还原过程中的粉化现象得到了改善,用CaBr_2作为浸泡液时尤其如此。另一方面,当烧结矿在CaF_2悬浮液中浸泡后,几乎测不到其RI和RDI值的变化。
